Lanes of the Road
Service Providers

- Defense Information Systems Agency
- Computer Emergency Response Teams
- Designated Approving Authority
- System Administrators

First we\'ll turn to the Service Provider lane. Representative service providers include Defense Information Systems Agency, or DISA; Computer Emergency Response Teams, or CERTs, from each service; and each network Designated Approving Authority, or DAA. System administrators can be viewed as service provider representatives. But, as we shall see, they fall into other lanes, as well. Generally, System Administrators have the responsibility of protecting their computer networks. This function is not limited to DoD systems, although there are some critical distinctions. DoD system administrators are subject to the Fourth Amendment, as they are performing a government action. On the other hand, they do not provide a communications service to the public, hence, are able to share information gathered from DoD systems, as opposed to the restrictions placed on public Internet Service Providers \(ISP\) by the Electronic Communications Privacy Act.
